ExcAVnTiNG-MAGHINE.

Specification of` Letters Patent No. 26,601, dated" becember2'3ii1859l To allwhofm it 'may concern: i i i l o' Be it known that I, THOMAS R. MAnKiL- LIE, ofVVinchester, `in the county of Sco-tt and State of Illinois, have invented a certain new and useful Improvement in Machines for Elevating Dirt &c., of which the following is a full, clear `and exact description, reference being had `to the accompanying drawing of the same, makingpart of' this specification, in whiche Figure 1, represents a plan of my `iinproved machine; Fig. 2, an end view; Fig.

3, a side elevation of one sidepFig. 4, a

similar view of the other.

In agricultural pursuits, itis an `object of paramount importance that the machinery employed be simple of constructionklight, cheap, strong and durable, and `so `far as is consistent with these prerequisites susceptible of application to the most varied uses.

Bearing these points in View, the object of my invention is to construct a machine which can be adapted to the digging of ditches, excavating of canals, raisingembanlrments and formation of roads &c`., and it consists first in the arrangement and combination of a plow with an elevatingwheel of peculiar construction; and secondly in combiningwith these devices,` a c arrier for elevating and transporting the dirt to the place required, at which it is to` be deposited.

In the accompanying drawing, the ma` chine is represented as consisting of a frame work (A) mounted on two wheels (B` `and C), the smaller wheel (I3) turning on a journal secured in a frame beam (b) hingedatoiie end to the main frame (A) andcon` nected at its other end by a link (c) to the end of a lever (d), pivoted `to the upper end of a slotted standard (e), secured to. the main frame, through the slotted `end of which the frame beam` l l of `the i wheel passes. The wheel thus mounted can be ad justed so as to suit the nature of the ground, and adapt the machine to it, a rack bar (f) being mounted on one of the cross beams into the notches of which the end ofthe lever is made to take, to maintain the wheel in the required position; a spring bar (g) being attached, at one end, to the side of the lever, in such manner as to embrace the rack bar (f) and thus retain the lever in whatever notch it may have been placed.

On the inner side of the rail of the main frame (A) next the large or carrying wheel (C) are formed or otherwise secured `two lugs or projectionsf(v),to is two rails connectedf,together` byfrods,"

a carrier or elevatorl (D)inadelin anyg i able manner,f in thisinstance,consisting` fr which are mounted `friction rolls atjprop rtf distances apart around' which afcoritinuo sf l belt or apron (E)ispassed,motionbeing@ l imparted to this belt,by;nie`ans of a belt passing around a pulley (`y`)w`iiiounted` onthe i end of the spindle or` shaft, of theouterfroll; anda driving pulley (It)"securedtolrtliefendl i of .the shaft (Z) of"all(,(OVTii` which meshes into the teeth of` a i drivin wheel (n) secured to theshaft of x he wheel C), whichas` theflatterlrevolves,ast it traverses over the'ground, imparts"niotoil` to the endless apron or belt of the elevata (D) as before mentionedi" i fuif A l )n the upperside of thennerrail ofi` 7(5) main frame are erectedtwo standards strongly braced in `the line of strain by `braces i im (o) `rising fromwthe. enten` railr,` Through the end of one of these Standards llforHI-Iiedi i a hole through which oneeiid of; cord r` rope (p) is passedand"secured,l`whenceit is carried around a friction roll `mtiiinted i on a clamp" (r) `secured to the outerend of the elevator (D) and`the1ice `ovenari-f` other roll, secured in theiupper end of th 85` other standard anduthence aroundw winch (s) secured totandcworlinguin the` same standard; byqturningfwhich inth ite-f quired direction theoiiterend of thefe` yaf tor may either be raisedyor` lowered, alsfutlieilQO` l circumstances of the caseniay dictated H is 'to say, `according totlieyheiglititrsirequired to` raise the: dirt. To( the outen end" and under side `of `thiselevator is hinged chute or slide I-I) bygineansgofisuita ey95 pendeln@` (I)- frmly Secured t0 its Side?, `ndl which is i held; at any required `angle 1to1 1the M elevator, byineans of abhool; (t) attachedt o the extreme end of the elevator ftakingln o i holes (u) pierced at suitableintervals apart 10`0- in the side of the chute, or `instead of one` hook two maybe used, one `at eithermside.` By this arrangement it wllbe apparentthat i o just as the heightfcf the outer end `of the chute is `raised or lowered so will the dis-11051 tance at which theldirtis deposited from 1 the machine be increased or di1ninished,fcare` i c being had not to `raise it` to a horizontal 3" plane, as, then, the `dirt wouldonly collect" i and not be depositedat all. Or instead of 1110` the chute being hin ed t the elevator, iti may be made to sli e out land `infor the l vided with a side beam- (K) which passes through metallic or other straps secured-to the drag beam L of the frame; and stayed with a brace (w). To the outer side of the pole is hinged a reversible plow ((M), by means of a drag link the mol boards of the' plow being so Varranged and con structed as to throw the dirt, as raised, into thewheel; the plow being vmade reversible so that, when the machine is used, it'need Y not be turned, when it comes to the end of the trench or ditch, but the polev simply unhitched and attached to the other end of the machine and the plow reversed to prepare it for operation again; previous to which however the parts of the wheel must also be reversed, the construction of which I will now describe.

The wheel is formed with a hub and heavy spokes as in other wheels but is provided with a very broad tread to the inner edge of which is secured a ange (y) to pre-- vent the dirt as it is cast into it from the plow, running out at that side as the wheel revolves. Midway or thereabout between the hub and tread is secured a metallic conical ring (N) having its lesser diameter next the elevator, and its greater diameter on the outside. -On the outer and inner side of this ring is arranged another of similar form, but narrower, into holes in which are ypassed rods (z) of wings (O) hinged to and in the line of the length of the spokes (P), so that by causing this ring to perform a partial revolution it will cause these wings to assume an angle to the spokes according to the direction in which the ring is turned. In operating the machine these wings being always inclined so as to prevent the dirt Vfrom slipping out in the outside of the wheel, as they are raised by its advance over the ground, and so as to incline it toward the chute (S) on the inside of the wheel so that the dirt, &c., may slide down from the wings on the latter, and thence by the inclination of the chute deposited on the endless apron or belt and by the latter elevated, carried and discharged at thepoint where it is l By the arrangement of the plow on thev 'one side of the pole, and the carrying wheel on the other the drag of the former will compensate for that of the latter and thus equalize the strain upon the horses or oxen. When it is not desired to operate the machine, but simply to transport it from place to place, a hook (l) is secured to one of the standards on which the plow is suspended at a suiiicient height above the ground to prevent it from throwing dirt into the wheel.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is-

l. The combination of the carrying wheel (C) as constructed and operated with the reversible plow, as arranged for the purposes set forth.

2. In combination with the carrying wheel (C) and plow (M) I claim the elevator (D) as arranged and operated for the purposes described.

3. I clairnV the hinged wheel frame (b) as arranged and combined with the lever (d) and rack bar (f) for the purposes set forth.

In testimony whereof, I have hereunto set my hand to this specification.
